This invention relates to paper punches I vided" with ;a' gauge rule 141 which and more particularlyto a deviceior punchin sheets or cards to enable application b thereof to binders and the like; i 1 I An important object of the invention is to provide a device ofthis character in which the dies and punches are readily g interchangeable toperinit variation'iof the :type of opening formed in thepaper. i A further object of'the invention is to produce a device of this characterwhich is adapted to form a plurality of. openings in-a 1 sheet, but which maybe very readilyladjustedto adapt the samefor use in punching a single opening 'in' the sheet or t'o vary the space between the openings which are formed. p 1 These and other objects I' attain by the construction shown in the accompanying drawings, wherein for thepurpose of illus tration is shown a preferred embodiment of my invention and;wherein: I Figure 1 is a vertical sectional view througha paper punch constructed intaccordance with my invention taken on the line 1 1 of Figure 2; 5

Figure 6 is a rear elevation of one type of punch; f

Figure 7 is a bottom plan view of the punch holder; Figure '8 is a of the punch and tie holders removed illus trat-ing the adjustability of the paper stops "carried by these elements;

Figure 9 is an enlarged plan view of a die; Figure 10 is a vertical sectional view through the die.

Referring now more particularly to the drawings, nates a base to receive the paper to be punched, the rear portion of which is downwardly ofiset, as indicated at 11, and adapted for attachment to a suitable support 12,

base 10 has along one The paper receiving stop 135E421 the paper thereo'fie side section of the punch holder with thepunch detail side elevation ofone the numeral 10 generally desigand adjacent the downwarduofiset :is pro extends transversely thereon.

A ENTomen-Y] Extending upwardly fromopposite ofthe downwardly oflset portion are stand-u ards 15, the vupper endsof which arepro- -vided;with openingslofor thereception of the pivots 17, which pass through ears 18 01 an operating handle 19 embodying a transversely extending bar 20, to theflendslof which theearslS are connected. Below the pivots 17, the standards receive the ends ofa stationary shaft 21 having mounted thereon arms 22 having clamping engagement with the shaft, as at '23,,so that they maybe I secured in longitudinally:adjusted positions thereon. Theouterend of each arm 221is provided withatransversely extending head,

generally desi'gnatedat 24, having its lower i surface '25 adaptedto flatly abut the upper surfaceofthe downwardly ofi'setv portion 11 in one position of thershaft andljthus limit rotative movement of the arms'about the 'shaft in this direction. 'Eachehe'ad' has in v -whatisits, front face when invsaid position -atransverselyextending slot 26, the lower wall of which is coplanar with the upper :p'ortion'of the paperreceivingbase whenlthe head is in such position and this slot is of sufficient width to permit insertionofa paper pile of the desired thickness. The head above and belowthe slot 26'is providedwith vertically aligned bores 27 and128 and the bore 27 has'communicating therewith a vertically extending slot 29iformedin'the head and terminating shortof the lower end of that portion ofvthe/head' lyingjabove the slot.

Slidable in the bores 27 are punch holders 28, each having in its lower end a bore 29, for the reception of the shankof a punch 30. The bottom'surface of each punch holder is formed with a slot 31 radial to the bore 29 and adapted to receive the upper end of the flange 32 of a keyhole punch. Each punch isiheldin position by a setscrew 33,

the outer end of which operatesin the slot 29 andpreventsrotation of the punch and punch holder.v This set-screw further serves to prevent dislodgment of a spring 34, which surrounds the upper ends of the punch holders 28 and hasit-s upper end engaged with a transversely extending in 35 carried thereby when the punch hol era are removed from the bores 27. The upper ends of the punch holders are rounded, as at 36, for engagement with the bar 20 of the handle.

The lower ends of the bores 28 are-enlarged, as at 87, to receive the flanges 38 of dies 39, which will, of course, correspond in character to the punch 30 which is being em ployed. The die illustrated in Figures 9 and 10 is of that type adapted for use in connection with keyhole punches and has a central aperture lO for the passage of the body-of the die and a radial slot '41 for the passage of the web thereof. These dies are held in position by set-screws 42 extending through whatare the rear faces ofthe heads when in normal position. It willbe obvious that these set-screws will' be readily accessible when thearm 22 is bodily rotated, so that the head lies to the opposite side of the-shaft-from that which it normally occupies; as i 'llustrated-in- Figure 4, so that these 'd iesmaybe removed and replaced.

Each arm 22 has adjustably mounted thereon a slotted bar as having at its forward end a depending finger 4A, which bridges'the slot 26 and forms a stop for the edge of the paper. As shown in Figure l, the upper ends of the punch holders will clear the" bar- 20 in one position thereof, so that the rotation of the arms necessary to render the set-screws 42 accessible may be accomplished by siinply loosening the securing elements of the clamps.

Since the construction hereinbefore set forth is capable of a certain range of change modification without materially departing; from the spirit of the invention, Ido not limit myself to such specific structure except as hereinafter claimed.

opposite endsof the downwardly offset portion, a shaft mounted in said standards,

arms adjustabl'y secured to said shaft'and each halving at its outer end a transversely bore in its lower end for the reception of the shank of a punch, the bore 'of the head within which the punch holder operates having a slot and a securing element extending th'rough the wall of the punch holder for engagen'i'ent with the shank of a die having its end extended for en a ement in theslot of the head to thereby hold the die and die hol'de'r against rotative movement with relation to thehead.

2. In a paper punch and in combination, a base having the rear portion thereof downwardly offset, standards arising from opposite ends of the downwardly offset portion, a shaft mounted in said. standards,

arms adjust-ably secured to said shaft and each having at its outer end a transversely extending head which flatly abuts the upper surface of the downwardly offset portion, said heads having slots formed in the forward faces thereof the bottom walls of which are co-plana-rwith the upper surface of the higher portion of the base, the head at opposite sides of the slot having vertically aligned bores for the reception of a punch holder and a die and a handle pivoted to the standards having a portion for engagement with the punch holders mounted in said heads, said portion of the handle in one position thereof permitting rotation of the "arms about the shaft to invert said heads.- I r In testimony whereof I hereunto aflix my signature.
